This is the second case I have heard of it. I have never seen one in person but don't doubt there may have been a few built. It likely would have been at the request of a high level factory executive that wanted one for themselves. They got what they wanted even if they would not built one for the public. Certainly all of the components were factory assembly line readily available so it would not be a big deal to do.

If the car has a broadcast sheet that will tell you if it was factory built.

Really Daryl? What if the car in question has one of your bogus home made Broadcast Sheets? Heck anything's possible right?
